Abstract
A film assemblage of the self-developing type which has a pair of upper and lower carrier sheets in juxtaposed relationship to one another. A pair of openings is provided in each of the carrier sheets. A photosensitive sheet and a positive receiving sheet are joined to outer surfaces of the upper and lower carrier sheets; respectively, so as to cover the respective openings. The pair of upper and lower carrier sheets is fixedly joined together in overlapping relationship, whereby the photosensitive and receiving sheets are in superimposed and spaced apart relationship thereby forming, in combination, an image area of the film.
